Title: Remote services console for digital data processing system
Inventor: WU HUIFENG E
IPC: H04M11/06
Filed: 1987-12-17
Granted: 1991-12-17
Abstract: ABSTRACT OF THE DISCLOSURE     A remote services console for transferring communications data among a console port and communications port of a digital data processing system, the system console and a remote services center which provides remote maintenance and diagnostic services.  The remote services console operates in three operating modes.  In one mode, communications data is transmitted directly between the communications port and the remote services center and between the console port and the console terminal.  In a second operating mode, communications data is transmitted between the console port and the remote services center through a microprocessor, the microprocessor being able to insert protocol data into the communications data transmitted to the remote services center and stripping the protocol data from the communications data received from the remote services center.  The protocol data serves to ensure proper transmission of communications data to and from the remote services center.  Under some circumstances the communications data may be copied to the console terminal, and the console terminal may transmit communications data to the remote services center through the microprocessor.  In a third operating mode, communications are effected between the communications port and the remote services center through the microprocessor.

Title: Non-aqueous solventless polyester varnish
Inventor: SASSANO DANIEL R
IPC: C09D167/06
Filed: 1987-12-29
Granted: 1990-12-18
Abstract: ABSTRACT OF THE DISCLOSURE       In a method of making a non-aqueous solventless polyester  varnish,  a  composition  is  prepared  which comprises about one mole of maleic anhydride, about 0.25 to about 0.35 mole of dicyclopentadiene, about 0.65 to about 0.75 mole of ethylene glycol, and about 0.35 to about 0.45 mole of polyol.  The composition is heated to about 150 to about 170°C, and then to about 200 to about 210°C, which condenses out water, forms an unsaturated polyester, and reduces the  acid  number  to less  than  about 45.   The composition is cooled to a temperature below about 150°C, and about 0.1 to about 0.5% of an inhibitor is added to said  composition,  followed  by  an  unsaturated  aromatic compound which can be styrene, vinyl toluene, or mixtures thereof, in a ratio of about 20 to about 40 pbw unsaturated aromatic compound to about 60 to about 80 pbw unsaturated polyester.  When it is desirable to use the composition, 0.5 to about 1.5 percent by weight of a catalyst is added to the  composition.   The composition  is applied  to a rotating apparatus and is cured at about 150 to about 160°C for about 45 to about 60 minutes.

Title: Traveling guillotine
Inventor: ANDERSON CHARLES D
IPC: B26D1/60
Filed: 1988-03-07
Granted: 1991-05-21
Abstract: TRAVELING GUILLOTINE            ABSTRACT OF THE DISCLOSURE          An apparatus (10) particularly suited for use for purposes of effectuating the cutting to length of continuous lengths of relatively thick, soft stock sheet material (14) such as sheets of styrofoam which have a thickness of six inches or greater.  The subject apparatus (10) includes a carriage assembly (32) mounted for movement on a support base (16).  The carriage assembly (32) is driven by motor means (34) operatively connected thereto.  The motor means (34) is operative to cause the carriage assembly (32) to move in a triangular path while undergoing movement in two planes at a speed which varies directly with the speed at which the soft stock sheet material (14) that is to be cut to length in the subject apparatus (10) is fed therethrough.  A knife means (68) is supported on the carriage assembly (32) for movement therewith such that as the carriage assembly (32) moves in a triangular path the knife means (68) likewise moves in a triangular path, i.e., down and forward. In order to effectuate the cutting therewith of the continuous length of soft stock sheet material (14) the knife means (68) at the time of cutting must be made to move at the same speed as that at which the continuous length of soft stock sheet material (14) is moving.  Thus, since the knife means (68) follows a triangular path of movement, the knife means (68) must be made to move along this triangular path at a speed which is 1.414 times the speed of the soft stock sheet material (14) that is to be cut therewith.

The print heads (81,83,85,87,89 & 92) may be offset longitudinally to permit closer line spacing and "start times" of individual lines adjusted accordingly.

Abstract: Abstract of the Disclosure A servicer is described for supplying two cut-to-length strips of sidewall simultaneously to a tire building drum without handling by the tire builder, thereby eliminating any stretching of the sidewalls or distortion of the shape of the sidewalls which can happen when the sidewalls are physically handled by the tire builder.  The servicer employs twin cassettes which contain two spools of spirally wound sidewall which is separated by a comparatively rigid, U-shaped protective liner.  The servicer has an indexing table for moving twin cassettes from a standby position to a let-off position to a take-up position and, lastly to a removal position where the cassette is removed for rewinding with new material.  A robotic grabber is provided to engage the leading edges of liners on a let-off cassette and move them to the rear of the servicer where the operator threads the liners onto a take-up cassette and the sidewall onto a pair of overhead belt-type conveyors for transportation to a discharge tray which is mounted on the front end of the servicer for rotation to and from an adjacent tire building drum.  The discharge tray carries a mechanism for cutting the sidewall, to length, and a device for finally aligning the cut sidewall for passage from the tray onto the sidewall area of an unvulcanized tire carcass being built on the drum.

Abstract: Envelope  for  a  dimensionally  stable  tobacco portion matched with the tobacco-receiving volume of a cigarette,  in particular a filter tip cigarette,  said envelope consisting of a completely smokable material and being permeable to air to an extent that the tobacco portion as such is unsmokable and becomes smokable only after being tightly wrapped into cigarette paper or the like.  In order to enhance the optical acceptance and to avoid any changes in flavor, the envelope is formed by a non-woven fabric predominantly produced from tobacco plant fibers so that practically the complete tobacco portion consists of smokable tobacco.
